To avoid the environmental consequences of extracting and processing virgin materials by using recycled and reclaimed materials.
Use materials for new infrastructure such that the sum of the post-consumer recycled content, on-site reused materials and one-half of the pre-consumer recycled content constitutes at least 50% of the total mass of infrastructure materials. Count materials in all of the following infrastructure items, as applicable:
- Roadways, parking lots, sidewalks, unit paving, and curbs;
- Water retention tanks and vaults;
- Base and sub-base materials for the above; and
- Rainwater, sanitary sewer, steam energy distribution, and water piping.
